Tempest Shadow would be the first pony to tell you she's not worthy of friendship. All she deserves after a life spent helping the Storm King conquer and pillage is four walls, bars, and solitude. But she's getting a new life in Ponyville anyway, at the side of Twilight Sparkle, Princess of Friendship.

Tempest Shadow isn't a friendship kind of pony. She's not a party kind of pony. She's not a happy kind of pony in the least. So what could there possibly be for her in Ponyville? More than she thinks, as it turns out. Come join her as she discovers what she's truly meant to do, what she's truly worth, and who she's truly meant to be with. Her life is going to change far more than she ever would have expected.

Searching for any records King Sombra may have left behind, Twilight learned of the shadowy king's tragic past. However, she also discovered his horn, in which his mind and remaining power were contained. Determined to learn how to use his Dark Magic for Good, Twilight brought Sombra back to Ponyville with her. After all, what could he possibly do as a horn? ...Or will he stay that way?

Canterlot lies steeped in chaos, a virulent and deadly plague still boiling away after a decade of suffering. The city, and the ponies in it, still feel the effects, still feel the bite of the times. The lower city, cursed as it is, is mostly partitioned off, leaving each and every pony left stranded and without help. Ponies struggle day by day just to stay alive.

Even as the ponies suffer, politicians toil away, plotting and scheming, machinations rumbling just below the surface. The city is fevered, sick and bloated, ready to pop at any moment. A single pony may be enough to make it all erupt.

And make it erupt Twilight Sparkle shall.

One small step, one lucky break is all she needs to turn the city on its head and take her rightful place by the Queen's side. But even she may not be prepared for the shark tank that is Luna's court.

All Twilight had to do was finish Starswirl the Bearded's final spell. She didn't have to become undead, seal her soul in the Elements of Harmony, or enlist her friends in an effort to fix everything... but you have to play the hand you're dealt.

Even if it's rotting off.

Big ups to Themaskedferret for all her support on this story.

The Everfree forest is just like any other forest—except it's full of monsters and weird magic junk, but ignoring that—it sometimes grows out of control and needs to be trimmed a bit. In order to keep the forest from growing too large, Celestia asks Twilight to start a controlled forest fire to burn a portion of it down. It seems like a simple request, but a series of mishaps and misunderstandings lead to some miscommunication and, subsequently, to Twilight setting fire to all of Equestria.

[Complete! With TVTropes apparently!]
Also, apparently, an animated trailer.

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

This story is a sequel to Upheaval: Breaking Point

Following the events of Breaking Point, Twilight Sparkle and her friends discover that Equestria's demise may not come from an enemy invasion, but from within. The Barrier Lands and the Heartland begin the slow and uneasy process of reuniting into a single Equestria, but this long-delayed joining is already in danger at its conception.

With Celestia's power in her grasp and her agents by her side, the wheels of Black Rose's plans for Equestria's future continue to turn. However, her brazen gamble has done more than just bring down a centuries-old barrier. Ancient powers begin to stir: the remnants of a dark period in Equestria's history, the immortal inhabitants of Celestia's homeworld, and a rising tide of darkness coming ever closer.
